Answer:

A) 4216.21621

B) 2646.363

C) 10325.094

Step-by-step explanation:

A) Step 1: Multiply 24 * 65 which = 1560... This then makes the fraction \frac{1560}{0.37}

    Step 2: Divide 1560 / 0.37 which = 4216.21621 (your answer)

B) Step 1: Multiply 71 * 8.2 which = 582.2... This then makes your fraction \frac{582.2}{0.22}

    Step 2: Divide 582.2 / 0.22 which = 2646.363 (your answer)

C) Step 1: Multiply 49.3* 11.1 which = 547.23... This then makes your fraction \frac{547.23}{0.053}

    Step 2: Divide 547.23/0.053 which = 10325.094 (your answer)

Should have offered more points, but hey, hope this helps!

In a random sample of n1 = 162 males, there are x1 = 63 people that have blue eyes. In a random sample of n2 = 333 females, ther
sesenic [268]

Answer:

z = 2.1784 > 1.96,

Reject the null hypothesis

Step-by-step explanation:

For the males:

n1  = 162, x1 = 63

P1 = x 1/ n1 = 0.3889

For the Females:

n2 = 333,

x2 = 97

P 2 = x2/n2

= 0.2913

P 1= P2 Null hypothesis

P 1 is not equal to P 2 alternative hypothesis

Pooled proportion:

P= (x1 + x2) /( n1+ n2)

= (63 + 97) / (162 + 333)= 0.3232

Test statistics :

Z= (p1 - p2) /√p(1-p)× (1/n1 + 1/n2)

0.3889- 0.2913 / √0.3232 × 0.6768 × (1/162 +1/333)

=2.1784

c) Critical value :

Two tailed critical value, z critical = Norm.S .INV (0.05/2) = 1.960

Reject H o if z < -1.96 or if z > 1.96

d) Decision:

z = 2.1784 > 1.96,

Reject the null hypothesis

A number is 2/3 if another number. the sum of the numbers is 50. find the numbers
slava [35]

A number is 2/3 of another number.  Both added together equals 50.

One of these numbers consists of three parts, and the other consists of two of those three parts.  So, there are 5 equal parts in total.

Thus we need to divide 50 by 5.  50 divided by 5 equals <u>10</u>.

The first number, which has three parts, is 30.  The second number, which as two parts, is 20.

I hope this makes sense to you.  :D  Good luck in all your studies!

What Is the slope of the line on the graph?
sashaice [31]

Answer:

1/2

Step-by-step explanation:

To find out this problem, you do rise over run to find the slope. First choose two points that are directly sitting on a line. I used (-2,1) and (0,2). Then count the rise, up 1, then the run, over two and that's how you get your answer. :)

I NEED HELP ASAP PLZZZZ
KonstantinChe [14]

Step-by-step explanation:

We just subsitue 3 for x and -4 for y, so we get

3(3) - 5( - 4) = 9 + 20 = 29

So

a = 29

7(3) + ( - 4) = b

21 - 4 = 17

b = 17
